s3, removing cotton sugar: adding 0.1-0.3 part of alpha-galactosidase into 20-40 parts of supersaturated sucrose solution obtained in the step S2 after ultrasonic treatment, stirring for 15-30 min at the temperature of 20-80 ℃ and the rotating speed of 500-700 r/min to obtain supersaturated sucrose solution after removing raffinose;
s4, forming sucrose microspheres: adding 1-3 parts by weight of epichlorohydrin into 20-30 parts by weight of supersaturated sucrose solution obtained in the step S3 after removing the raffinose, and stirring for 8-12 min at a rotating speed of 200-400 r/min to form a water phase A; adding 2-4 parts of span 80 into 4-6 parts of liquid paraffin, and stirring for 15-25 min at a rotating speed of 200-400 r/min to obtain an oil phase B; dripping 0.1-0.3 part of organic acid and 4-6 parts of oil phase B into 20-30 parts of water phase A at the speed of 1 drop/second respectively, stirring at the temperature of 35-50 ℃ and the rotating speed of 800-1000 r/min for 1.5-3.0 h to form uniform emulsion C, adding 0.5-1.5 parts of glutaraldehyde into 20-35 parts of emulsion C, and standing at the temperature of 35-50 ℃ for 1-3 h to obtain a mixed sugar solution containing sucrose microspheres;
s5, crystallizing; transferring 15-25 parts by weight of the mixed sugar solution containing the sucrose microspheres obtained in the step S4 into a round-bottom flask, placing the round-bottom flask in an ice bath condition, controlling the ice bath temperature to be 0-2 ℃, carrying out low-temperature rapid crystallization for 20-40 min at the rotating speed of 500-700 r/min, filtering, and drying the crystal in an oven at 50-70 ℃ for 6-10 h to obtain microsphere inclusion;
the organic acid is at least one of citric acid, alpha-linolenic acid, stearidonic acid, eicosapentaenoic acid, conjugated linoleic acid, gamma-linoleic acid, arachidonic acid, oleic acid, trans-oleic acid, eicosenoic acid, erucic acid and nervonic acid.
